' WATER-WHEEL.

Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed February 4, 1905. Serial No. M LIOQ.

To all whom it may concern:

Be it known that I, OBED HAND NORDSTROM, a citizen of the United States,residing at Punxsutawney, in the county of Jefferson and State ofPennsylvania, have invented certain new and useful Improvements in'Water- Wheels, of which the following is a specification, referencebeing bad therein to the accompanying drawings.

My invention relates to water-wheels, and more particularly to thatclass of turbinewheels wherein the water operates upon a series ofblades or buckets, one of the objects being to provide a device of thecharacter described wherein the water shall be conveyed against and uponsaid blades or buckets through a plurality of channels, each channelleading directly into the chamber in which the buckets are arranged andby reason of which a number of streams of water will en gage with saidblades or buckets simultaneously.

A further object of my said invention is to procure a device of thecharacter described in which the water can be automatically turned onthrough a number of channels by operating the valve to one of thechannels and whereby it may be turned off by the same means.

A further object of the invention is to provide a valve that may be alsoused as a cutting-blade and which acts as such when weeds, grass, orother growth comes in contact with said valve, thereby keeping theentrance therea to constantly free from such obstructions.

A still further object of the invention is to provide means to overcomethe resistance offered by the valve sticking in the valve-seat andwhereby the valve may easily be operated.

' Further objects and advantages of the invention, as well as thestructural features by means of which said objects are attained, will bemade clear by an examination of the specification, taken inconnectionwith the accompanying drawings, in which the same reference-numeralsindicate corresponding portions throughout, and in which- Figure 1 is aside elevation. Fig. 2 is a central vertical section. Fig. 3 is a detailof the wheel carrying the buckets. Fig. llis a detail elevation of oneof the valves. Fig. 5 is a detail side elevation of the double cams atthe top of the valves. Fig. 6 is a top plan. Fig. 7

detail elevation illustrating the adjustment of the lower bearing of themain shaft, and Fig. 10 is a sectional view showing the ball-bearingsbetween the double cams.

l designates aframe in which is adjustably mounted a platform 2,supporting a shaft 3, having an enlarged base 3', said shaft carryingthe cylinder 4, which has secured thereto or formed integral therewiththe bucket-blades is adapted to rotate.

8 designates openings in the platform 2 beneath the ball-bearings inorder that sand which may accumulate in the races in which the balls areadapted to rotate may be washed out, leaving the races-clear andunobstructed.

The water is given ingress to the bucketblades at four points, and asthe arrangement of parts by means of which the Water is conducted to theblades is similar in each a de scription of one will suflice for all.

A gear-wheel 9 is loosely mounted upon the shaft 3, said gear-wheelbeing engaged by a cog-wheel section or segment 10, having a number ofcogs thereon adapted to fit those upon said wheel 9. This cog-wheelsection 10 is rigidly mounted on a shaft or stem 11, which has rigidlysecured thereto or formed integral therewith a valve 12, having anopening 13 with sharp cutting edges 14, said valve being mounted to turnin a cylindrical valveseat 15, having openings 16 to admit the water,which passes into a chute 17, where it is These bucket-blades arecam-shaped, being narrow at the top and wide at the bottom and arecovered by a plate 18, rigidly mounted on top of the cylinder 4 andwhich effectually holds the water within the chute. The peculiar shapeof the chute 17 causes the water to form a wedge by means of which it isgiven an extra force, all of which is exerted against the bucket-blade,which being spiral in shape has also the weight of the water upon it,which augments the force against it, and which weight necessarilyincreases as the water approaches the lower end of each bucket-blade,the volume of water being greater at the lower end than at the upper.The shaft or stem 11 turns in a plate 19, rigidly mounted on, the frame1 and having thereon a cam projection 20, engaging with a correspondingcam projection 21, rigidly mounted on saidshaft or stem, the twoconstituting a double cam. Each of said cam projections 20 and 21 has anadjustably-mounted cam-ring 22 of any suitable material and held inplace by the setscrews 23. Ball-bearings 24 are interposed between thecam-surfaces and are held in place by said cam-rings, the edges of whichextend beyond the cam-surfaces 20 and 21, the balls traveling in a racein the cam-surfaces, as shown. The object of this last-describedarrangement of parts is to provide means for slightly raising the valve12 in turning it in order to lessen the strain caused by said valvesticking in the valve-seat as the valve is given a vertical movementsimultaneous with the horizontal.

The shaft 3 is mounted at its upper end in roller-bearings 25 and turnsin a casing of' Babbitt metal 26 to avoid wear and at the same time topreserve precision in the operations of said shaft. The platform 2,carrying the ball-bearings 8, upon which said shaft 3 rotates, isadjustably mounted in a frame 27 by means of the set-screws 28. Theobject of this last-mentioned arrangement of parts is to provide a meansfor keeping the shaft true at all times, so that if any of the partsbecome worn and the shaft thereby becomes out of plumb it can bereturned to a perfectly vertical position by said arrangement.

Connected with the main frame 1, in which my said device is mounted andwhich constitutes a part of it, is a box or flume 29, which surroundsthe entire device and carries the water to all of the openings 16, sothat it may be turned on at all points simultaneously.

In operation the valves are opened by means of a hand-wheel 30, mountedon one of the shafts 11, motion being imparted to the remainder of saidshafts 11 by means of the gear-wheel 9, which engages with all of thecog-sections 10, as heretofore stated. When said valve 12 is opened, thewater rushes in, as indicated by the arrows pointing to the opening, andcomes in contact with the bucketblades 5, as heretofore explained, anddescends upon said bucket-blades and passes out, as indicated by thelower arrows in Fig. 1, into a fiume 31.

Having thus described my said invention, what I claim as new, and desireto secure by Letters Patent of the United States, is-
